He arrived in Australia in 1857 and travelled to the
Darling Downs where his deceased brother, Ernest Elphinstone Dalrymple, had been a pioneer of British colonisation establishing the
Talgai pastoral run in 1840. Hoping to acquire land, George instead became a
sheep station superintendent, managing James Charles White's
Jondaryan property. In 1858, he was appointed to the position of a local magistrate by the colonial government.
1859 expedition to the Burdekin River In 1859 Dalrymple led an expedition to assess the uncolonised
Burdekin River catchment area for pastoral occupation. This group included
Ernest Henry,
Philip Frederic Sellheim, Robert Phippen Stone, James Hood and Richard Haughton which left
Rockhampton with two Aboriginal guides. The party travelled west through the region and then north to the
Valley of Lagoons, making surveys on the
Burdekin and
Suttor Rivers and marking out promising runs for sheep. Ernest Henry and James Hood made their way back early to present their land claims, shooting at various local Aboriginal people and setting a dog upon them along the way. Dalrymple and his remaining men followed the Burdekin River through difficult terrain and monsoonal weather to the coast at
Upstart Bay. Here, they had two skirmishes with a large group of resident Aboriginal people which involved the expedition members charging at them on horseback. The expedition returned to Rockhampton in March 1860. The area Dalrymple explored was known as the Kennedy district which was in
New South Wales when the expedition started but on returning it had become part of
Queensland which had been
declared a separate colony. The new
Queensland Government rescinded Dalrymple's claims to land in that region, but in compensation Dalrymple was appointed to the position of
Commissioner of Crown Lands for the Kennedy district.
1860 expedition to Cleveland Bay and Port Denison In 1860 Dalrymple led a second expedition north, this time by sea. He was accompanied by Lieutenant Joseph W. Smith, Robert Phippen Stone and
Eugene Fitzalan on the schooner . They landed on
Brampton Island where they encountered some Aboriginal people and soon after traded with two Aboriginal men in a canoe near
Hook Island. They arrived in
Port Denison in September and Stone Island, in Bowen Harbour, was named after R. P. Stone. Dalrymple noted that the banks of the
Don River near the harbour were lined with Aboriginal camps indicating a "very thickly" inhabited area. Because of this, he did not meet Morrill. They landed on the shore near to where the modern city of
Townsville now stands and met with a number of Aboriginal people, giving them biscuit and tobacco. The Aboriginal people then started to touch and feel all the expedition members, and began "smacking their lips", which Dalrymple interpreted as an indication that they wanted to eat them. Another group of Aboriginal people came down, attacking them with a shower of stones and spears. Dalrymple and his men "were necessitated" to fired upon them, "repulsing them with loss." They landed again near to
Cape Pallarenda to obtain surveys from the hilltops but decided to descend to their awaiting dinghies as they noticed residents of three Aboriginal camps below were moving in their direction. These people were yelling and dancing "in a very hostile manner" and Dalrymple felt obliged to fire upon them. Dalrymple's group then made an "orderly retreat" to the dinghies halting at intervals to fire upon those throwing spears. The crew which had remained upon the
Spitfire had seen about eight armed Aboriginal men in canoes approaching them from nearby
Magnetic Island in an apparent attempt to board the ship. They were repulsed by a discharge of the brass gun. The maritime group arrived first and waited for Dalrymple's overland party by camping on Stone Island at the mouth of the harbour. Dalrymple's group, which included 140 horses and 121 cattle, arrived on 11 April 1861. He rode down to the area on the foreshore in order "to clear off the aborigines from the same, should such be necessary" and to signal McDermott's group on Stone Island. The local people had already fled. The settlers on Stone Island then came over and the town of Port Denison (later called Bowen) was founded. Dalrymple wrote that it was "deeply gratifying to me to see the British flag flying over the spot where..a few days ago, the wild aboriginal held undisputed sway" and that the settlement marked "the advance of another great wave of Anglo-Australian energy."
1862 expedition to the Burdekin River In 1862, Dalrymple made another journey to the lower
Burdekin River region concluding that the "richly grassed open forest country" would become "a most valuable addition to the pastoral and agricultural resources of the colony." This area was soon after opened up to pastoral occupation and later became the
sugarcane growing region around the present day township of
Ayr.
1864 expedition to establish the town of Cardwell In January 1864, Dalrymple led an expedition to establish a port and township on the shores of
Rockingham Bay. This port was to facilitate transport access to the
Valley of Lagoons Station about 80 km inland. Dalrymple was part of the company that established the Valley of Lagoons Station in 1862 after the area was opened up by the government. A partnership formed between
Walter Jervoise Scott, his brother Arthur, Dalrymple and
Robert Herbert (then
Premier of Queensland) financed the acquisition of the leasehold. The partnership became Scott Bros, Dalrymple & Company with Dalrymple acting as manager. Dalrymple's group consisting of twenty men, including Captain
Walter Powell, Lieutenant
John Marlow of the
Native Police,
Philip Frederic Sellheim and
James Morrill, set out from Bowen on board the
Policeman. They arrived in Rockingham Bay and on 21 January, Dalrymple chose the most adequate site available for the new port. Morrill, who had a good knowledge of the local Aboriginal dialects after living with a nearby clan for 17 years, was asked to convey to the Aboriginal people that the group had come to take possession of the area. Dalrymple also found a very neat village, bora grounds and pathways of these native residents. The new British port settlement was named
Cardwell after
Edward Cardwell, 1st Viscount Cardwell, the
Secretary of State for the Colonies at that time.
1864 expedition along the Herbert River After establishing the site of the new township of Cardwell, Dalrymple set out to make a route to the Valley of Lagoons Station. After following a native path and cutting through thick jungle along the range behind Cardwell, the group found a valley of grassy plains intersected with bands of rainforest. A river meandered through this valley, which Dalrymple named the
Herbert River after his business partner and first
Premier of Queensland,
Robert Herbert. Dalrymple followed this river, which was inhabited by a tribe of Aboriginal people, up into the
Seaview Range and to the Valley of Lagoons
sheep station. Here he obtained supplies, men and livestock, and made a difficult journey back to Cardwell, expanding the path into a road of sorts. Land along the Herbert River valley was soon taken up by colonists and the town of
Ingham was later established. ==Politics==
